D500 - darktable basecurve / tonecurve


(/ar) #1

Looking for a darktable basecurve + tonecurve for d500.

I produced one following an older explanation (link) and the README in …/tools/basecurve however I’m not too hapy with the basecurve - and the tonecurve is way off.

darktable still does not include any model-specific basecurve for this cam.

Wondering if anyone has come across a reasonable good basecurve for the cam and could share it

These are the ones I have.
